this one was from several years ago but I have another one now about the same size. (2x6 planks on the dock for size comparison) Always been at least one in my pond and always male. several decades ago there was one about 10' long that my dad fed chicken to tied to the end of a long cane pole but he got too aggressive and dad shot him, back when they were strictly protected. Took it around and showed everyone in town but never got caught with it.
The Tx game folks tell me the small males can't fight for females against the big bulls in the river (2000' ft from the pond) so as juveniles, they try to find a pond to grow up in then return to the river to claim their share of the girls. I've seen them snag a lot of wood ducklings and bass frequently but they won't bother turtles. Evidently don't like the taste of beaver either. Cold blooded and they hibernate in winter in burrows but in early spring come out and like to lay in the sun and hunt mostly at night. Their eyes will shine in a spotlight.
